WALLACE L. HALL ANLD RICHARD F. GEORGE, OF SAN FRANCISCO, CALIFORNIA.

PORTABLE GAS-RANGE.

Specification of Letters Patent.

Patented Sept. :5, .1913.

Application filed September 12, 1911. Serial No. 648,871.

To all whom it may concern:

Be it known that we, VVALLACE L. HALL and Riot-Iain) F. Gnonon, bothcitizens of the United States, residing in the city and county of SanFrancisco and State of California, have invented new and usefulImprovements in Portable Gas-Ranges, of which the following is aspecification.

This invention relates to improvements in a portable gas stove or range.

It is the object of this invention to provide a light and compact gas oroil range which :an be readily moved from place to place by hand, andwhich is adapted for use in baking, boiling, steaming, frying andotherwise cooking and preparing foods, etc.

Another object is to provide in a range of the above character, a simpleand e'llicient means for distributing heat throughout the interior ofthe even from a single burner.

Other objects will appear hereinafter.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure 1 is aperspective view of the invention with parts broken away. Fig. 2 is avertical longitudinal section of same.

In the drawings A represents a rectangular base supported on legs 2 andhaving an upwardly extending flange 3 on its outer edge, and ispreferably formed of cast metal. The oven portion of the invention isconstructed of sheet metal, and the sides are formed with double walls4-4), with the intervening space filled with a non heat con doctor orinsulator 6, such as asbestos, to confine the heat to a large degreewithin the oven. One side of the oven is provided with a door 7. whichis also made double and lined with asbestos or other heat insulatingmaterial. The bottom 8 of the oven is attached to the sides thereof,while the top 9 is in the form of a plate having a downwardly extendingflange 10 on its outer edge, the top plate 9 being preferably formed ofcast metal and rests upon the upper edge of the sides of the oven withthe flange 10 overlapping the sides a short distance, as shown in Fig.2.

The top plate 9 is provided with openings 11 closable by means of lids12 in the usual manner. and a series of vents or perforations 13 areformed in a row along the front edge of the top plate to admit of theescape of a small portion of the heated air in the oven at this point.

In assembling the range the oven is set on the base A within the flange3 and the top plate 9 is set on the upper edge of the oven sides asbefore described, and bolts 13 are passed through the plate 9, betweenthe walls a t of the oven and extend through the base A; nuts 14: beingscrewed on the lower ends of the bolts 13 to bind the parts together. Abolt 13 is disposed near each of the four corners of the top plate 9.

Formed in the bottom 8 adjacent the back wall of the oven is aperforation 15 which is adapted to receive a removable hood 1G,constructed in the form of a truncated cone and having a peripheralflange on its lower edge which is adapted to rest on the bottom 8, saidhood having, also, a downwardly extending flange projecting into theperforation in to prevent sidewise shifting of the hood 16. The upperopen end of the hood 16 extends into a sheet metal flue 17, which fluenormally rests on the hood 16 and extends upward within the oven andterminates a short distance below the top plate 9 adjacent one of thecovered openings 11. Disposed within the hood 16 is a gas burner 18 ofany suitable description which burner is connected with a pipe 19through a needle valve 20. The pipe 19 is adapted to be attached to aconduit leading from any suitable source or gas supply not necessary tobe here shown.

The stem 21. of the needle valve 20 extends beneath the bottom 8 of theoven and through the flange 3 in the base A to the front of the range.and is fitted with the usual hand wheel 92 for operating the valve. toregulate the flow of gas to the burner 18.

A damper 95? is mounted in the fine 17 to regulate the flow of heat fromthe burner 18 to the interior of the oven. A perforation 24 is formed inthe fine 17 at its lower end through which a light may be readilyapplied to the burner 18 from the interior of the oven. this perforationbeing adapted to be closed by means of a downwardly projecting shield 25formed on a partition 26 arranged to he slid in or out of the oven inthe usual manner. This partition divides the casing of the oven into aplurality of compartments with each of which the flue l7 may he made tocommunicate, as we will hereinafter describe.

A series of removable shelves 27 are disposed within the oven above theshelf 26. in any suitable manner.

In the application of the invention, a light is applied to the burner 18through the perforation 24, the shelf 26 being previously withdrawn, thepipe 19 connected with the source of gas supply and the valve 20 opened.burner are impinged on the inner wall of the hood 16 and the heat risingdirect from the flames passes upward through the flue 17 and enters theoven through the upper end thereof, this direct heat acting to heat thetop plate 9 so that it may be used as a stove. The perforations 13insure the heat rising from the flue 17 passing along the underside ofthe top plate 9 so as to thoroughly act on the latter. The heatradiating from the hood 16 and flue 17 serves to heat the interior ofthe oven.

By making the hood 16 removable, it can be taken out and quicklyreplaced by a new one when it becomes warped or Worn by the intense heatof the flamesimpinging thereon.

A strap or band 28, mounted on the back wall of the oven, passes aroundthe flue 17 near its upper end and is attached to the flue by means of ascrew 29 in such manner as to securely hold the flue 17 against movement or displacement; the flue 17 being held rigid acts to retain thehood 16 in place. The lower end of the flue 17 is flared outwardly so asto readily fit the upper end of the conical hood 16 and form a tightoint at this point without necessitating the use of rivets,'screws, orother devices for connecting the hood 16 and flue 17 together.

The apron or shield 25 formed on the underside of the partition 26 andextending over the opening 24:, forms a closure therefor to prevent theescape of the heat through this opening. "When it is desired to permitthe heat to pass through this opening into the space below the partition26, the latter is inverted and the damper 23 is closed,

which then acts to direct the heat through the perforation 24 to theunderside of the shelf 26 which is preferably formed of an imperforatesheet of metal. It will thus be seen that the partition 26 divides theoven easing into a plurality of compartments, and the flue, 17, for theheating agent is formed with a plurality of outlets which communicatewith said compartments, the partition being adjustable and carrying theapron or shield as'a means for varying the discharge of the heatingagent through the respective outlets of the flue according to thevarious adjustments of the partition.

Having thus described our invention what we claim and desire to secureby Letters Patent is 1. In a portable gas range the combina- The flamesemanating from thetion of a base having an upwardly extending flange onits outer edge, an oven resting on said base, having a separable topplate, said top. plate having a series of perforations near one edge,and said oven having a perforation in the bottom, a removable hooddisposed over said last perforation, aflue resting on said hood andopening to the interior of the oven near the top plate thereof, a gasburner disposed in said hood and mounted on the base, said flue havingan opening adjacent its lower end for the insertion of aflame, and adamper in said flue above said opening, substantially as described.

2. in a portable gas stove, of the character described, the combinationof a base, a removable oven supported on the base, said oven having itsbottom plate provided with an opening nearthe back thereof, a downwardlyflared hood removably fitted to said opening and extending into the ovenchamher, and having a flange fitting said opening whereby the hood isprevented from side movement, a flue fitted to the upper end of the hoodand extending to a point in the oven near the top thereof, said ovenhaving a top plate with vents therein for the escape of products ofcombustion, and a' gas burner in said base and entering the lower end ofsaid hood.

3. In a portable gas stove of the character described, the combinationof a base, aremovable oven supported on the base, said oven having itsbottom plate provided with an opening near the back thereof, adownwardly flared hood removably fitted to said opening and extendinginto the oven chamher, said hood having a vertical flange at its bottomfitting said opening whereby the hood is'prevented from sidemovement, aflue fitted to the upper end of the hood and extending to a point in theoven near the top thereof, said oven having a top plate with ventstherein for the escape of products of combustion, and a gas burner insaid base and entering the lower end of said hood, said flue having anopening in one side, means for opening or closing said opening toprevent or allow the passage of heated air through the opening into thelower portion of the oven, and a damper in the flue above the openingfor controlling the passage of heated air through the flue.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
